New York Sen. Hillary Clinton's margin over Sen. Barack Obama among Ohio likely Democratic
primary voters has shrunk to 49 - 45 percent on the eve of the state's March 4 balloting, according
to a Quinnipiac University poll released today.

This compares to a 55 - 34 percent Sen. Clinton lead in a February 14 poll by the
independent Quinnipiac (KWIN-uh-pe-ack) University and a 51 - 40 percent lead February 25.

Sen. Obama has made gains in the last week especially among men and black voters.

The gender gap is a key factor in this latest survey, as women support Sen. Clinton 55 - 39
percent, while men back Sen. Obama by a mirror image 55 - 39 percent margin. Clinton's strength
among lower income voters, 50 - 44 percent, and among older voters, 55 - 39 percent, also gives
her an edge over Obama.

The Illinois Senator leads 58 - 37 percent among voters under 45. He also gets 90 percent
of the black vote, while Clinton leads 60 - 34 percent among whites.

"The profiles of the Clinton voter and the Obama voter in Ohio are almost mirror images,"
said Peter Brown, assistant director of the Quinnipiac University Polling Institute. "Men are for
him; women for her. Those higher on the socio-economic scale are for him; those lower for her.
Older people are for her; younger voters for him.

"The big unknown is turnout. It's not just whether it is higher than normal, which everyone
expects it to be. The key question is whether turnout is disproportionately higher among some
demographic groups than others."

"Sen. Clinton always has had a gender gap, but the 22-point difference between her
support among white men and white women is extraordinary," said Brown. "She is ahead overall
because women have made up 55 to 60 percent of primary voters in most Democratic primaries.
That is a considerable advantage for her."

Clinton's margin among those without college degrees, which had been 57 - 34 percent
February 25, has narrowed to 51 - 43 percent. Obama's support among those with sheepskins,
which had been 58 - 33 percent in the last survey, also has dropped, to 49 - 45 percent.

Self-identified Democrats voting in this primary give Clinton a 49 - 44 percent margin,
while independents who are likely to vote in the Democratic primary go 50 percent for Obama and
48 percent for Clinton.

"Sen. Clinton is still ahead, but her presidential ambitions depend on whether those who
have been her supporters resist jumping on the Obama bandwagon and go to the polls for her," said
Brown.

There is strong loyalty for both candidates, with 88 percent of Clinton supporters and 86
percent of Obama backers saying their mind is made up.

From February 27 - March 2, Quinnipiac University surveyed 799 Ohio likely Democratic
primary voters with a margin of error of +/- 3.5 percent.

The Quinnipiac University Poll, directed by Douglas Schwartz, Ph.D., conducts public
opinion surveys in Florida, Pennsylvania, New York, New Jersey, Connecticut, Ohio and the
nation as a public service and for research.
